autoconf (2.61-1) unstable; urgency=low This package should be largely compatible with older Autoconf releases back to 2.50, and especially with 2.59 and later. Please read NEWS for details. Two changes bear especial emphasis. First, quoting from the upstream NEWS: > ** Directory variables adjusted to recent changes in the GNU Coding > Standards. The following directory variables are new: > > datarootdir read-only architecture-independent data root [PREFIX/share] > localedir locale-specific message catalogs [DATAROOTDIR/locale] > docdir documentation root [DATAROOTDIR/doc/PACKAGE] > htmldir html documentation [DOCDIR] > dvidir dvi documentation [DOCDIR] > pdfdir pdf documentation [DOCDIR] > psdir ps documentation [DOCDIR] > > The following variables have new default values: > > datadir read-only architecture-independent data [DATAROOTDIR] > infodir info documentation [DATAROOTDIR/info] > mandir man documentation [DATAROOTDIR/man] > > This means that if you use any of `@datadir@', `@infodir@', or > `@mandir@' in a file, you will have to ensure `${datarootdir}' is > defined in this file. As a temporary measure, if any of those are > found but no mention of `datarootdir', the substitutions will be > replaced with values that do not contain `${datarootdir}', and a > warning will be issued. This has proven to be a problem in some cases where the advice in the manual is not followed. Please refer to the "Defining Directories" node in the manual, titled "How do I `#define' Installation Directories?", for more details. (The manual can be obtained by installing the "autoconf-doc" package from the non-free distribution that accompanies Debian.) Here is a second item that bears mention, again from upstream NEWS: > ** AC_PROG_CC, AC_PROG_CXX > No longer automatically arrange to declare the 'exit' function of C, > when a C++ compiler is used. Standard Autoconf macros no longer use > 'exit', so this is no longer an issue for them. If you use C++, and > want to call 'exit', you'll have to arrange for its declaration > yourself. But we now suggest you return from 'main' instead. -- Ben Pfaff Sun, 26 Nov 2006 09:13:19 -0800
